Web OS platforms -> 4 major players


in Hanselminutes an MS guy and a Java guy point out that there are 4 major potential Web platform standards, i.e. Web Apps’ runtimes:

  • MS Silverlight (as J. Spolsky talked in StackOverflow podcast lately: Silverlight is going to be the Windows Mobile Apps main engine)
  • Sun Java, especially with the new applet plugin rewrite and JavaFX (replacing Swing) which also runs the same code on desktop (J2SE) and mobile (J2ME)
  • Adobe AIR – runtime for Flash, Flex (ActionScript)
  • Google GWT (?), which runtime is JavaScript (!) – and this is most interesting, since they base on HTML5 and JS, so they don’t need any plugin, only a W3C conformant browser

10:20 – „[…] in lot of cases explanation problems come from a reliance on the people that know the most about something being the ones responsible for explaining it […] in the book Made To Stick by Chip and Dan Heath there a passage in there about what they call The Curse of Knowledge. […] the experts, it’s really hard for them to put themselves in the learners’ position […] and then what do we do when we need to explain something? – ‚Aahh. Ask the inventor. Ask the expert.’

It’s hard to be a tapper. The problem is that tappers have been given knowledge (the song title) that makes it impossible for them to imagine what it’s like to lack that knowledge. When they’re tapping, they can’t imagine what it’s like for the listeners to hear isolated taps rather than a song. This is the Curse of Knowledge. Once we know something, we find it hard to imagine what it was like not to know it. Our knowledge has „cursed” us. And it becomes difficult for us to share our knowledge with others, because we can’t readily re-create our listeners’ state of mind.

The tapper/listener experiment is reenacted every day across the world. The tappers and listeners are CEOs and frontline employees, teachers and students, politicians and voters, marketers and customers, writers and readers. All of these Groups rely on ongoing communication, but, like the tappers and listeners, they suffer from enormous information imbalances. When a CEO discusses „unlocking shareholder value,” there is a tune playing in her head that the employees can’t hear.


P2P backup


while listening to IT Conversations | Jon Udell’s Interviews With Innovators | Phil Libin on EverNote I got this idea inspired by latest P2P services like money lending…

I try to replicate my most valuable data into several locations, but there’s always the threat that several is not enough. Lately, online servers are most common storage for my personal data. And, though I believe in e.g. Google’s backup policy, I felt like I should do more about it. So… how about replicating backups via P2P?

Just like in file swapping (backup can be 1, archive file) duplicate you precious data in as many locations as possible. The only difference is that it’s more like push (upload) than pull (download) in traditional swapping.

– So who’d like to host my data and what’s his business in it?
– Well, JWL sang: „I scratch your back, you scratch mine”.

– And what about privacy?
– Isn’t PKI enough? And „there’s alway a bigger fish”… than Blowfish 🙂

Also some specs I can think of now:

  • a backup may be fragmented (if too large) – also, since we need instant backup and rarely a recovery , fragmenting may be an optimal solution – and so it is in e.g. BitTorrent
  • if snapshot replication is not enough, incremental approach may also be supported
  • a priority of a backup may be set by it’s owner and respected by the network (community) for distributing and storage lasting
  • there may be a TTL for each archive fragment
  • the number of distributed locations you may use is proportional to the array size you offer for hosting (may be a part of a disk partition 🙂

that’s the idea – maybe I’ll get back to it later…

Aaaaahhh… should’ve known I was scooped > … I still haven’t got that „GGL first” reflex yet 😛



after this podcast i checked out the video…

really jaw-dropping

He works mainly in developing countries where the dominant computer is the cellphone, and the dominant network protocol is SMS, a phenomenon that he calls „the invisible computer revolution.”

  • 16:34 – „[…] it’s actually kind of comical how twitter is the hottest thing on the block right now… and so suddenly all those people with their, you know, 2 GHz computers and, you know, huge displays are sending them each other, you know, basically text messages over the Web, right? – isn’t that interesting?[…]”
  • 26:38 – on olpc: ” […] I don’t understand why we need a program… to spend millions of dollars to make laptops cheaper… when laptops get cheaper every day… you know, I mean, that will be like setting a World Bank program to make water flow downhill … „

IT Conversations: Stefano Mazzocchi


IT Conversations: Stefano Mazzocchi

Stefano Mazzocchi, the creator of Apache Cocoon, is now an MIT research scientist working on SIMILE, a series of projects that take a pragmatic, grassroots approach to bootstrapping the semantic web. The SIMILE team has learned that you can’t mandate coherence. But when people can create and mix data to suit their own tastes and purposes, it may emerge.

some interesting points:

  • 06:05 – „(Apache) Cocoon started to lose a little traction when the browsers became more and more powerful” (i.e. XSLT available at client side)
  • 20:14 – ” […] data first, instead of structure first […] when conceptualizing something you don’t know a priori how the structure is gonna turn out be […] a lot of people use spreadsheets as databases – you write down whatever you want and then you can incrementally add structure to it […] it’s much more bootstrapable approach to data modeling than it is the top-down design driven, schema driven approach […] „
  • 34:40 – „[…] peer pressure […] huge kinda social incentive at this point […] the only possible way […] that the stuff is ultimately ever going to take off […] it’s that incentive system […]”
  • 35:14 – „[…] unlocking this chicken and egg problem […] a lot of the Semantic Web researches were based on big hypothesis, that was: ‚If whatever then you could do this’ […] it’s like ‚if we have all the world in OWL then we could do inferencing engine’ or ‚when everybody use Dublin Core then …’ „
  • 37:26 – „[…] you have to have your tools that work at individual levels before they can work at group levels […] create a smooth transition between the data that is useful for individual, but can also grow to be useful to a group […] without that transition […] you’re always stuck in this when they show up – we can party […]”
